When should the evaluation of erectile function be done before radical prostatectomy?

Area of Science:

• Urology
• Andrology
• Sexual Medicine

Background:

• Erectile function is crucial for quality of life in men undergoing prostate procedures.
• Transrectal ultrasound (TRUS) biopsy is a common diagnostic tool for prostate cancer.
• Assessing the impact of TRUS biopsy on erectile function is important for patient management.

Purpose of the Study:

• To evaluate changes in erectile function following transrectal ultrasound prostate biopsy.
• To determine the optimal timing for assessing erectile function in patients considered for radical prostatectomy.

Main Methods:

• 44 patients undergoing TRUS biopsy were assessed.
• The International Index of Erectile Function-5 (IIEF-5) questionnaire was used.
• Patients completed the IIEF-5 before biopsy and at 4 weeks post-biopsy.

Main Results:

• 50% of patients were potent before the biopsy.
• After 4 weeks, 66% of patients reported erectile dysfunction (mild to severe).
• The decline in erectile function post-biopsy was statistically significant (p < 0.05).

Conclusions:

• TRUS biopsy has a significant, albeit temporary, negative effect on erectile function.
• Erectile function assessment using the IIEF-5 is recommended before TRUS biopsy.
• This timing provides a more accurate baseline than assessing before radical prostatectomy.
